Comparing: Object 907A vs. Object 430

The decision to start development of a next-generation medium tank was made on July 13th, 1953. Development was carried out by Research Institute No. 100. The project was submitted in March 1954, and at the beginning of 1955 the hull of the new vehicle was tested for shell resistance. However, later the project was canceled.

A prototype of this medium tank was developed from 1953 through 1957 to replace the T-54. Soviet authorities wanted a tank with greater nuclear survivability and firepower, so in 1961 the project was discontinued in favor of the Object 432. Several prototypes of the vehicle were manufactured.
